Push to talk provides direct voice communication connected with the push of a key. Use push to talk to have a conversation with one person or with a group of people. Before you can use the push to talk service, you must define the push to talk access point and push to talk settings. You may receive the settings in a configuration message from the push to talk service provider. In push to talk communication, one person talks while the others listen from the built-in loudspeaker. Speakers take turns responding to each other. Because only one group member can talk at any time, the maximum duration of a speech turn is limited. The maximum duration is usually set to 30 seconds. For details of the speech turn duration for your network, contact your network operator or service provider. Phone calls always take priority over push to talk calls. Besides the packet data counters, the phone registers only one-to-one calls in the recent calls lists in Log. The participants should confirm the reception of any communications where appropriate as there is no other confirmation of whether the recipients have heard the call. To check availability and costs, and to subscribe to the service, contact your network operator or service provider. Note that roaming services may be more limited than home network services. 115
